FAQ
What is the lug width of the Rolex Datejust 31 ref. 178274-0091?
The Rolex Datejust 31 ref. 178274-0091 has a lug width of 16mm. This measurement is specific to this 31mm case size and should be verified with a digital calliper before purchasing any aftermarket strap.
What is the best strap for the Rolex Datejust 31 178274-0091?
For a white gold and steel case with a fluted bezel, fine-grain alligator belly leather is the most formally coherent choice. Alternatively, vegetable-tanned box-calf leather develops a distinctive patina over time. The recommended clasp is a butterfly deployant in steel or white gold, 16mm.
How do you change the strap on a Rolex Datejust 31?
Strap replacement requires a fine-tipped springbar tool suited to Rolex lugs. The Datejust 31's 16mm lug profile demands a precise tool to avoid scratching the white gold case. It is advisable to have the strap changed by a watchmaker or a specialist atelier.
Are there aftermarket straps compatible with the Rolex Datejust 31 ref. 178274-0091?
Yes. Any aftermarket strap with a 16mm attachment is technically compatible. Milano Straps offers a curated selection of handcrafted leather, rubber and exotic leather straps made specifically for 16mm lugs, with buckles and deployants in steel or gold finishes.
How long does a leather strap last on a Rolex Datejust 31?
Longevity depends on the material and care. A quality alligator strap, conditioned periodically with a neutral cream and kept away from direct moisture, will last between 3 and 5 years with daily wear. Vegetable-tanned box-calf can last even longer, developing a characteristic patina. Milano Straps products carry an 18-month guarantee against manufacturing defects.
